4.0: Installation (continued)
4.2: Operational Environment
This section discusses the type of installation required depending on the electrical
environment.

option and will give good performance in this environment.
Standard equipment wire such as 7/0.2 (24AWG) can be twisted together as re-
quired. Standard data cable such as generic CAT5 UTP will also give good perfor-
mance.
4.2.2: Industrial Environments
Typically, this will be an industrial environment where there is equipment likely to
produce high levels of electrical interference, such as welders, machine tools, cut-
ting and stamping machines.
Connections should be made using screened cable. Braided or foil screened cables
may be used. The cable screen should be connected to the LDX-4 case at cable
entry point. The case of the LDX-4 should be connected to a local ground. An EMC
cable gland is recommended. This is supplied with the LDX-4.
When selecting the type of wire or cable to be used, consider the following param-
eters:
- Screening.
- Conductor size (resistance).
- Mechanicalaspectssuchasexibilityandrobustness.
This is not a complete list. Installations may require other special cable characteris-
tics.
4.3: Electrical Connections
The LDX-4 requires three connections.
1. Transducer.
2. Power Supply.
3. Output Signal, Voltage or Current.
A small hole should be made in the grommet prior to passing the wires through. If
a screened cable is to be used, an EMC cable gland is recommended (see section
4.7).
